GEORGE GARLAND GLENN, OFGASTONIA, NORTH CAROLINA. 7 MACHINE FOR RESI- IAPING BOTTLE-CAPS.

Specification of Letters Patent.

Application filed September 2. 1905. Serial No. 276,858-

Patented July 17, 1906.

To all whom it may cancer-m" I Be it known that I, GEORGE GARLAND GLENN, a citizen of the United States, re-

siding at Gastonia, in the county of Gaston and State of North Carolina, have invented a new and useful Improvement in Machines for Reshaping Bottle-Caps, of which the following is a specification.

.The object of-my invention is to provide a simple and practical machine for reshaping previously-used crown-caps for bottles and at the same time inserting new cork disks therein; and it consists in the novel construction andarrangement of suchmachine,which. I will now proceed to describe with reference to the drawings, in which Figure 1 is aside elevation of the entire machine, partly in section. Fig. 2 is an enlarged sectional view of the feeding and fitting device for inserting the cork disks into the metal caps after reshaping the latter, and Fig. 3 is a detail of the die-seat.

In the drawings, Fig. 1, the numeral 1 resents a table mounted on legs 2. Supported upon the table is a cast-metal frame 3, having sliding bearings 4 4, in which slides a vertical plunger 21. This plunger is conrep- nected by a pin and slot with the short end of a lever 6, fulcrumed at 7 to the framework and whose outer end is connected to the vertical rod 8. The lower end of this rod is jointed to an elbow-sha edtreadle 12, and this treadle is fulcrume to a pendent support 11, which is formed as a part of the cast frame 3 and extends centrally down through and below the table 1. Y

is a turn-table mounted on a vertical pivot 19 in a bearing in the frame, so as to occupy a horizontal plane and rotate about itsvertical pivot. The plunger 21 constitutes the punching-die for reshaping the caps,

- This pawl is jointed at the middle to the upper end of the vertical arm of an elbow-lever 13, fulcrumed at 19 to the pendent portion 11 of the metal frame. To hold this pawl into engagement with the ratchet-teeth, a

- the magazine to the turn-table bi spring 14' connects the opposite end of the pawl to the horizontal arm of the elbow-lever 13. The outer end of this arm of the elbow-lever 13 lies between two collars 9 and 10, secured to rod 8 by set-screws, so that as this rod rises and falls the collars 9 and 10 vibrate the lever 13 and cause the pawl 15 to alternately advance beneath the ratchetteeth and on the return movement to enga e the ratchet-teeth and move the turn-tab e the distance between two die-seats, so as to successively bring the latter with their contained caps beneath the plungendie. The'vertical reciprocation ofrod 8, it will be seen, operates the vertical lunger- 21 and also rotatesthe turn-table. n addition to this it also feeds the disks of cork from a m azine into the reshaped metal caps on t e.

turn-table. This is accom lished as follows:

Two collars 17 and 18 are ixed to the rod 8 by means of set-screws, and between them is received the horizontal arm of a bell-crank J fulcrumed to the metal frame 3. The vertical arm of this bell-crank connects with a horizontal rod J which extends past the plunger to a position'directly above the turntable and works a cork-feed device, as follows: 5' is a stationary horizontal armprojecting from the lower bearing of the plunger and having at its outer end a stationary quadrantal frame. This frame is best'shown in Fig. 2. It consists of a curved slotted plate V E, connected at opposite-ends by members E E? to a curved stationary slideway. C. This slideway at its lower end extends to a closely-tangential position to the turn-table immediately above the row of cap-seats in the turn-table, one of l which cap-seats is shown formed in a movable die I). The lower portion of said stationary slideway is formed with a hole'through it large enough to admit the passage of a cork disk therethrough. The

upper end of this slideway has attached to it a horizontally-projecting tubular magazine I for containing a series of the cork disks, shown at A, which cork disks are pressed inwardly by a s iral spring H behind them.

The corkriisks are fed successively from the reciprocation of rod Jfl'as follows: T e rod J is jointed to a crank-arm J, which is attached to the axis of an oscillating quadrantal frame composed of radial arm D and tube K (which are ninety degrees apart) and a curved guard-plate D, which lies flat against and par- C and also extends allel with the slideway feed end of the over and covers the inner magazine I.

The tube K has a plunger B in the same, which is forced downwardly by a spiral spring G, located above the end of the lunger within the tube, and the lower end 0 said tube is made larger than the other portion to accommodate the enlarged head of the plunger. A pin F is secured to the plunger and projects laterally through a slot in the plunger-tube, and the end of said pin"(which is preferably provided with a roller plays in the curved slot of plate E. This slot is formed to the curve a true circle throughout its upper portion; but at its lower end. at e, just above the hole in slideway C, said slot extends downwardly, so as to allow the pin F (andthe plunger B) to descend whenever the plunger B attains a position above the hole in slideway C.

The operation of my machine is as follows: The magazine I is loaded from its inner end with cork disks a. The seats I) in the turntable are fitted with the metal caps by hand. Now at every operation of the treadle 12 the stamping or shaping plunger 3 and turn-table 15 are operated as before described and in addition the bar .l is reciprocated. This bar J oscillates the crank J and frame D l) K over the stationary slideway C. When the frame I) I) K is in its uppermost position, as seen in Fig. 1, the opening in tube K is immediately in front of the magazine I, and the spring II in the magazine forces a cork disk a into said tube, the plunger B being held back a distance equal to the thickness of a cork disk by the pin F in the curved slot of plate E. Then when the frame D D K moves down to the position shown in Fig. 2 as soon as the plunger B comes above the hole in slideway C and above a seat bin the turntable the pin F rides down into the offset part c of the s ot from the action of spring G and forces the cork disk a into the metal ca 0, which has been properly shaped by the p unger 21. The quadrantal extension of the guard I), it will be seen, serves in this movement to close the otherwise open end of the magazine and holds the other cork disks against the pressure of spiral spring H. i

The cork disk a is inserted into the metal cap after the latter is reshaped, the successive movement or movements of the turntable bringing them first under the stamping or shaping plunger 21 to swa e the cap upon the die-seat 1) into the shape or a second application to a bottle and then under the cor tting device. I preferably time the movements of the machine so that the shaping.- plunger 21 shapes a cap at the same time that the feed-plunger B inserts a cork into a previously-shaped cap.

I have found that the bottle-caps may as a rule be used four times to advantage; but it is not desirable to have them reshaped and used a greater number of times on account of the weakening of the metal flange from repeated bendings.

To prevent morethan the desirable number of reusings of the caps, I form the die-seat b with a little teat t, eecentrically placed, (see Fig. 3,) so that when a cap is reshaped it will receive a slight indentation in its exposed face, and no caps are to be reused which show more than four such indentations. By a little care on the part of the cap-feeder the caps may be easily inserted so that a previous indentation will not coincide with the teat in the die-seat. v

In order to insure the stopping of the turntable at the proper point to bring a die-seat b beneath the swaging-plhnger, a springseated pin 22 registers with a small cavlty 23, formed in the bottom of the turn-table immediately beneath each die-seat. When the turn-table rotates, this spring-pin is depressed and enters the next cavity when the latter reaches it.

Having thus described my invention, What I claim as new, and desire to secure by Letters, is I 1.
